Re: [OT] Process modelling (with Wicket front-end)

2008-10-09 Thread Daan van Etten


Hi Kaspar,

We use jBPM for our processes. We don't manage the processes from  
Wicket, as there is a nice plugin Eclipse for it.
jBPM uses Java and Hibernate, so you can create any GUI you like in  
Wicket and show underlying jBPM stuff (like tasks, processes, etcetera)


Regards,

Daan

Can anybody recommend a good process modelling tool that integrates  
with Wicket?


We would like to use such a tool for many activities in our  
organziation:


- We show processes to our end-users as part of our knowledge  
information centre
 website. So we need to present processes, interactively, if  
possible. The website
 (including the CMS front-end) runs on Wicket and ideally, we would  
like to

 edit the processes in a Wicket GUI, too.

- We are starting to provide e-learning solutions and there, too, it  
might be

 helpful to structure a course with a process modeller.

- We use processes internally for certain documents (in Alfresco CMS).

I have slightly touched jBPM as it is used in Alfresco CMS, and I  
have watched
the presentation http://docs.jboss.com/jbpm/v3/demos/movies/jbpm-overview.htm 

given at http://www.jboss.com/products/jbpm. Also, I have read a  
little about
YAWL and heard of BPDM but as I lack experience with these tools/ 
models, I
wonder: What state-of-the-art tools (in Java) are out there, and has  
anybody

managed to get integration with Wicket?

Thanks,
Kaspar

Re: Problem with upload (works on xp, error on linux)

2008-10-09 Thread Herbert Winter

hello,

thanks for your input, more info on this:
* I use wicket-1.4-SNAPSHOT.jar
* I checked out the code from the repository ... and build the
code...so it is not the exactly the same war...
* I pointed the upload dir to a dir in my home-dir with no
writepermissions, no luck of course
* I pointed the upload dir to a dir in my home-dir WITH
writepermissions, no luck again
* if I use the no-ajax-upload  from
http://www.wicket-library.com/wicket-examples/upload/ it does not work
on different machines running ubuntu 8.04 (desktop) and ubuntu 8.10
(beta, desktop).

What else could it be?

greetings

 If you haven't modified anything between the two wars, then it sounds
 like a rights issue. AFAIR some linux distributions restrict
 dangerous things such as reflection.

Sure.  Look at what the Label class does.  It doesn't have an HTML template.

Re: wicket + spring + jpa/ hibernate = lazy load exception

2008-10-09 Thread Nino Saturnino Martinez Vazquez Wael


Hi Lutz

I agree, there is something to this.. However it's not wicket related.. 
I know that Bjarni are hacking away at something, I've dicussed a few 
things with him.


I guess if you are creating entities then you can store your data in a 
temporary model... However Bjarni Gudmondurs thing(still under 
development, he will make post to his blog soon ) will remove the need 
for explicitly defining the temporary class. It follows the builder 
pattern and on the end of the form/wizard whatever you just call 
build... If you are editing stuff then a loadable detachable model 
should be okay if you just persist the changes on each request, if thats 
not okay. Because the editing needs to be confirmed first then you have 
to store your data in a temporary map or something and persist on 
submit.. Theres loads of different ways of handling this, with pros and 
cons. You could also put in an extended persistence context but there 
are performance/memory issues with this if you have too much data, and 
data will be persisted on the fly. But I actually like the fact that we 
get the lazy load exceptions. It tells us that we are not using 
detachable models and our entities have become stale...


Lutz Müller wrote:
It might work if you dont have any ajax on your page. otherwise each ajax call 
happens in a new request and causes your domain object to be retrieved from 
the database.
this way you lose every change made to your object. writing all changes to 
database before detaching can be an option, but then you might persist 
something to your datastore that is in the midst of being edited.
i would be glad to offer a solution to the problems i just brought up, but i 
am struggling with this problem ever since i started using wicket.

not for me, as the original entity is pulled using an
loadabledetachableModel via a SortedDataProvider :/

if you look around, the all called solution for this is the
OpenSessionInViewFilter and the usage of
bean id=transactionManager
class=org.springframework.orm.jpa.JpaTransactionManager
for that (latter one is used by me, too)

However, the OpenSessionInViewFilter will not work with wicket, even if
mapped to /* in the web.xml

Hi,

I'm currently struggling with the famous lazy load exception under
spring + jpa with wicket.

The problem is, in my case, that i pull an entity from the database
using a spring-bean (@SpringBean) and JPA (hibernate). Then in the
wicket class i need to walk the entity tree a bit, based on the needs
of the user (preloading wont work, as i dont know the direction the
user wants to walk and the whole entity tree is too complex to grab it
all at once).

If I use the Entity myEntity.getMyOtherConnectedEntity I get the lazy
load exception (transaction already closed). So I tried to use the
OpenSessionInViewFilter to solve this, but it just won't work - no
reason why, as the error stays exactly the same.

Currently I ended up using this:
@PersistenceContext(type = PersistenceContextType.EXTENDED)
private EntityManager em;

However, I'm not sure if this is the way it is supposed to be?
( I read so far that this disables a big part of springs-transaction
handling support but didnt see any impacts so far)

Has anyone a different aproach/ solution for this using wicket +
spring with JPA?

Best,

Korbinan

PS: im on wicket 1.4-m3

markup for component extending RadioGroup?

2008-10-09 Thread dukehoops


Hi,

I created a component MyRadioGroup that extends RadioGroup (has two Radios
inside). I cannot figure out what to put in MyRadioGroup.html. The following
does not work because it expects MyRadioGroup to be a Panel:
wicket:panel
 input wicket:id=radio1 type=radio/
 input wicket:id=radio2 type=radio/
/wicket:panel

Is the lesson here to only extend Panels (or FormComponentPanels) when
creating custom components that simply encapsulate other components?

thanks,
-nikita

Re: html code in component class


the label appears complex i looking for a simple solution

My custom componentuses wicket components internally  here is an example

protected class CustomLinkComponent extends  WebMarkupContainer  {

public CustomLinkComponent(String displayName, Class  clazz) {
super(customlink);
this.displayName=displayName;
this.clazz=clazz;

}

  the html  for this is   
# label wicket:id=lbl/label 

 so instead of writing a html page  i want my component to render this html
and further wicket should replace the child components  link and lbl with

Hibernate + HTML-Table

Hey there,

I want to execute a simple sql-count-query with a group by statement 
and display the result in a html-table...


something like:
   session = HibernateUtil.getSessionFactory().getCurrentSession();
   session.beginTransaction();
   String SQL_QUERY = SELECT COUNT(*),Date FROM Person Group 
By Date;

   Query query = session.createQuery(SQL_QUERY);


What is the best way to manage that, not using too much fancy stuff...?

Ajax update DefaultDataTable using textfield

2008-10-09 Thread taygolf


Hey guys,

I am trying to update a DefaultDataTable using a textfield and ajax. I have
done it to a ListChoice before but for some reason I can not get it to work
with a DefaultDataTable.

Basically what I want to do is have a textfield on my page. when the user
types a letter in the textfield I want to take that letter and update the
query that I send to my dataprovider. The dataprovider will then update the
DefaultDataTable.

I have place the DefaultDataTable in a WebMarkupContainer and I am updating
the query and then calling then setting the DefaultDataTable to the new
provider and the adding the WebMarkupContainer to the target of the
AjaxFormComponentUpdatingBehavior but it does not seem to want to work. All
of this is in a panel which might be causing some issues I am not sure.

Am I looking at this the right way ir is there somewhere else I need to
look.

All I really want is a DefaultDataTable with a searchbox at the top to
narrow down what is being shown in the Table.

Thanks

DownloadLink

2008-10-09 Thread Pablo Scagno

Hi, 
I was trying to use DownloadLink but for some reason  I couldn't make it work. 
I'm trying to insert the link in a grid, but when I test the application and I 
click the link, an error page appears The webPage cannot be found

this url appears in the page
http:///?wicket:interface=:7:table:rows:1:cells:2:cell:download::ILinkListener::

here Is the code where I create the link

public class ActionPanel extends Panel{ 
public ActionPanel(String id, IModelDocument model){
super(id, model);
try {
File file = ((Document)model.getObject()).getOriginalFile(); 
IModelFile fileModel = new ModelFile();
fileModel.setObject(file);
add(new DownloadLink(download,fileModel));
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
}

I've debug the app and I saw that the file was loaded, and the link was created 
without any problem. Can anyone tell me if need anything else to make it works?

Thanks in advance

Pablo

Re: html code

2008-10-09 Thread Timm Helbig

Hi,

1) I would choose a Panel

2) Sounds like Markup Inheritance would help you here. Create some Base Panel 
and then extend this class and the markup and include the different 
Components, if any.

Hope this helps

Timm

RE: html code in component class

2008-10-09 Thread Serkan Camurcuoglu

Peter means that you can put html as the string content of a label like this:

Label l = new Label(myLabel, ulliSome html here/li/ul);
l.setEscapeModelStrings(false);
l.setRenderBodyOnly(true);

this way the label will display only the html that you've given..

Is it staying as it is in m3? (Ive checked the generics page on the wiki).

AjaxButton submit url

2008-10-09 Thread Michael Oswell

I am curious if it is possible to change the URL that is used for the  
XMLHttpRequest so that I can force a form on a non-SSL enabled page to  
post to an SSL url.
In this particular case, I have a non-secure page with a login panel  
on it.  The form in the panel is using an AjaxButton for form  
submission, and I would like to have it post the login request over  
SSL so need to change the URL used in the request.


Possible?

thanks,

Re: Closing ModalWindow using javascript:window.close()

2008-10-09 Thread rmorrisey


RG,

I think that you can use top.window.close() if you are trying to close the
entire page. window.close() probably isn't working because ModalWindow uses
an IFRAME if I remember correctly.

If you want to close only the ModalWindow and not the entire window, I would
take a look at how it's done in ModalWindow.closeCurrent(AjaxRequestTarget).

HTH,
Russell

 not close modal window but it does work in regaular page.(i.e. if

CryptedUrlWebRequestCodingStrategy and bookmarkable page components

2008-10-09 Thread Ritesh Trivedi


Hi,

I am using CryptedUrlWebRequestCodingStrategy, which uses http session key
for crypting urls. I noticed an issue with this

Lets say customer was on the bookmarkable page and left that open for time
longer than the session expiration time. Now if the bookmarkable page has
components like DropDownLists or StatelessForms they wont really work
because the session was expired and they see a error page from the
bookmarkable page!! not very pleasant.

Am I correct in the diagnosis? if yes, would the solution be to create a
subclass of cryptedurlwebrequestcodingstrategy which would not crypt the url
if the parent of the component was bookmarkable page? or are there any
better ways of handling this?

 i would be glad to offer a solution to the problems i just brought up, but i 
 am struggling with this problem ever since i started using wicket.

The best is if you can use autosave and just persist everything
(valid) always. Often this (combined with undo when needed) is
also a good solution for the user.

If not, at least we are not using detachable models in places 
where editing needs to span several requests.

Other option would be to use separate data transfer object 
style form beans.

 creating custom components that simply encapsulate other components?

WebMarkupContainer, actually (Panel is fine if you want to 
enforce the component to have its own HTML). 

Does this cause a problem?

Re: Ajax update DefaultDataTable using textfield

 Basically what I want to do is have a textfield on my page. when the user
 types a letter in the textfield I want to take that letter and update the
 query that I send to my dataprovider. The dataprovider will then update the
 DefaultDataTable.
 
 I have place the DefaultDataTable in a WebMarkupContainer and I am updating
 the query and then calling then setting the DefaultDataTable to the new
 provider and the adding the WebMarkupContainer to the target of the
 AjaxFormComponentUpdatingBehavior but it does not seem to want to work. All
 of this is in a panel which might be causing some issues I am not sure.

It should be fine, we've done something like this using
DataView (for easier customising). 

To help you it would be important to have the problem in a
runnable quickstart (or at least see the code).

Re: Hibernate + HTML-Table

2008-10-09 Thread Michael O'Cleirigh


Hi Björn-Peter,

Have a look at DefaultDataTable which is part of the wicket-extensions 
module



|*DefaultDataTable 
http://wicket.sourceforge.net/wicket-extensions/apidocs/wicket/extensions/markup/html/repeater/data/table/DefaultDataTable.html#DefaultDataTable%28java.lang.String,%20wicket.extensions.markup.html.repeater.data.table.IColumn%5B%5D,%20wicket.extensions.markup.html.repeater.util.SortableDataProvider,%20int%29*(java.lang.String id, 
IColumn 
http://wicket.sourceforge.net/wicket-extensions/apidocs/wicket/extensions/markup/html/repeater/data/table/IColumn.html[] columns, 
SortableDataProvider 
http://wicket.sourceforge.net/wicket-extensions/apidocs/wicket/extensions/markup/html/repeater/util/SortableDataProvider.html dataProvider, 
int rowsPerPage)|


you put the Hibernate stuff into a service layer (so you can use the 
spring @Transactional annotation) and then have that called through your 
implementation of the SortableDataProvider.


The IColumn's define the columns that will appear in the table.

If you have a small number of results you could extract seperately and 
use the ListDataProvider (java.util.List list) to provide data for the 
table.


If you have a large data set you should implement your own version that 
pages through hibernate. add one of the toolbars to get this pagination 
functionality automatically. (dataTable.addTopToolbar (new 
NavigationToolbar()))


Regards,

Mike





I want to execute a simple sql-count-query with a group by statement 
and display the result in a html-table...


something like:
   session = 
HibernateUtil.getSessionFactory().getCurrentSession();

   session.beginTransaction();
   String SQL_QUERY = SELECT COUNT(*),Date FROM Person Group 
By Date;

   Query query = session.createQuery(SQL_QUERY);


What is the best way to manage that, not using too much fancy stuff...?

Cheers B

Re: How can I use the wicketdate-time stuff with DateTime on my model?

2008-10-09 Thread Patrick Angeles


We use DateTime/LocalDate in our entities as well. It's easy enough to roll
your own form components.

See the patch and zip file attached to this issue, you can probably just put
those classes in your own project and run with it.

https://issues.apache.org/jira/browse/WICKET-466

The patch is meant to handle java.util.Date, and Joda DateTime and LocalDate
all at the same time. Now that Wicket FormComponents are generic though, I
think it's better to just have separate FormComponents and Converters for
each class.

 I can see its internals are all DateTimey which is AWESOME!!
 
 What is the easiest / quickest way of getting this stuff to work with
 DateTime in my domain model.
 
 I'm running 1.4m1.
 
 What I'm toying with is compiling the project and applying the patch from
 http://issues.apache.org/jira/browse/WICKET-466
 
 But I'd rather have a simpler way - eg, extend or reimplement a class.

Re: wicket + spring + jpa/ hibernate = lazy load exception

Are we talking about a wizard here? What if you used something like this:

https://wicketopia.svn.sourceforge.net/svnroot/wicketopia/trunk/wicketopia/src/main/java/org/wicketopia/model/proxy/ProxyModelManager.java

Basically, the models cache their values until you call commit on
the ProxyModelManager. So, you can do as many steps in the wizard as
you want and if you base your components on proxied models (that wrap
PropertyModels around a LoadableDetachableModel), then your object
will only be loaded from the database at the end (during the commit
of the proxy models) and you won't lose your edits.

this way you lose every change made to your object. writing all changes to
database before detaching can be an option, but then you might persist
something to your datastore that is in the midst of being edited.
i would be glad to offer a solution to the problems i just brought up, but i
am struggling with this problem ever since i started using wicket.

The best is if you can use autosave and just persist everything
(valid) always. Often this (combined with undo when needed) is
also a good solution for the user.

If not, at least we are not using detachable models in places
where editing needs to span several requests.

Other option would be to use separate data transfer object
style form beans.

Best wishes,
Timo
